Question

A company offers customers two plans for Internet service.

Plan A: $30 for the modem and $5 per month for service.

Plan B: $20 for the modem and $10 per month for service.


Equations:

Plan A: _______________

Plan B: _______________


BONUS: After how many months will both plans equal the same? _______________

Answer 1

Explanation:

lets say you are paying for a year

A- it would cost you $30 on the spot and another 60 for the year

A=30$60= $90

A-$30+($5*t)

B- it will cost you $20 on the spot then another 120 for the year

B-$20+($10*t)

B=$20+$120= $140

t= 12

Answer 2

plan A: 5x+30
plan B: 10x+20
bonus: the 2nd month

explanation for bonus:
5(2)+30
10+30
=40

10(2)+20
20+20
=40

the first month plan A would cost $35. plan b would cost $30 the first month. So, the earliest month both of them would cost the same price would be the second month.

hope this helped <3
